H5N1 bird flu in England: zones and safety, Apr 2026

Here’s the week’s key change, explained for learners and keepers. On 14 April 2026, Defra confirmed highly pathogenic avian influenza (H5N1) in commercial poultry at a third premises near Gainsborough in West Lindsey, Lincolnshire, and at a site near Great Shelford in South Cambridgeshire. Protection zones of 3km and surveillance zones of 10km now surround each site, and the affected flocks will be humanely culled to prevent further spread.

If you’re inside a protection zone, you face the tightest biosecurity and movement rules for birds, eggs, by‑products, equipment and even mammals that live on site; many moves need a licence. In a surveillance zone, enhanced checks and record‑keeping apply and APHA teams increase monitoring. What this means for you: the zone on the government’s disease map sets the legal rules you must follow from the moment it’s declared.

Checking your status takes minutes. Open the official bird flu disease zone map, type your postcode and zoom to your premises. Then read the zone rules before moving anything off site; if movement is essential, check whether a licence is needed. Doing this first keeps you compliant and helps to cut transmission between holdings.

Housing measures were lifted on 9 April 2026, so birds can go outside again unless you’re inside a protection zone or a captive bird (monitoring) controlled zone. Mandatory biosecurity remains in force across England. Keep housing and kit clean, store feed and bedding under cover, and prevent wild birds from accessing drinkers and ponds.

What is H5N1, in plain English? It’s a type of avian influenza virus that mainly affects birds. ‘Highly pathogenic’ describes how severely birds are hit; it does not automatically mean high risk to humans. Low‑pathogenic strains (LPAI) also circulate but usually cause milder illness in birds.

Risk to people is, according to the UK Health Security Agency, very low. The Food Standards Agency also says the food safety risk is very low; properly cooked poultry and eggs are safe to eat. For students: this is first and foremost a disease of birds, and everyday activities like walking past a pond do not change your personal risk when you follow hygiene advice.

For context, this outbreak season runs from 1 October to 30 September. So far in 2025 to 2026 there have been 99 confirmed HPAI H5N1 cases across the UK and one LPAI case. England has recorded 78 HPAI cases (and one LPAI), Scotland nine, Wales seven and Northern Ireland five. Under World Organisation for Animal Health rules, the UK is not currently classed as free from HPAI.

A short timeline helps everyone keep track. On 11 April 2026, H5N1 was confirmed in commercial poultry near Market Rasen in West Lindsey, Lincolnshire. On 14 April, further cases were confirmed near Gainsborough and near Great Shelford. This is why we encourage a quick map check before any planned movement each day during an active response.

If you find dead or visibly sick wild birds, don’t touch or move them. Use the government’s reporting service for dead wild birds, and wash your hands with soap and water if you’ve been near droppings or feathers. The NHS provides accessible hygiene advice; the headline message is to keep your distance and report, not handle.

You can keep feeding garden birds, but keep feeders and water baths clean, as advised by the British Trust for Ornithology, and avoid spots close to premises that keep poultry or other captive birds. If an Avian Influenza Prevention Zone is in force where you live, you must not feed wild gamebirds within 500 metres of any premises housing more than 500 birds.

Avian‑origin influenza can infect wild and kept mammals too, and it is notifiable in both. If you examine or test a wild or kept mammal and suspect infection, or detect influenza A virus or antibodies, you must report immediately: in England call APHA on 03000 200 301; in Wales call 03003 038 268; in Scotland contact your local Field Services Office. Not reporting is a criminal offence.

Planning a bird show or event? Outside disease control zones, gatherings of pigeons, songbirds, parrots and birds of prey can go ahead under a general licence when conditions are met. Events involving chickens, turkeys, quail, ducks, geese or ratites require a specific licence, and no gatherings are allowed inside protection or surveillance zones.

Vaccination isn’t permitted for poultry or most captive birds in England. Zoos can apply for authorisation to vaccinate eligible birds, assessed by APHA. Defra and the Veterinary Medicines Directorate continue to fund research and track vaccine development through the avian influenza vaccination taskforce.

Quick glossary to teach with: a protection zone is a 3km area with the strictest rules; a surveillance zone is a 10km ring with enhanced checks; AIPZ means Avian Influenza Prevention Zone, where mandatory biosecurity applies; APHA is the Animal and Plant Health Agency; Defra is the environment department that leads the response; UKHSA advises on human health risk.

For classrooms and smallholdings, keep it simple and practical. Start with a five‑minute map check and a note of which zone you’re in today, review the zone rules before any movement, and make hygiene visible-clean boots, clean kit, covered feed. Encourage learners never to touch wild birds, and for keepers, consider APHA’s ‘stop the spread’ webinars to refresh your plan. What this means: calm routines, clear information, and quick reporting will protect birds and keep communities safe.
